Can I use a color correcting yellow .50 as a medium yellow filter?
I've a toy camera that I want to glue a gel filter to the inside so I always shoot with a yellow (k2) filter. Will an old Cibachrome color correcting filter do? If so which one? I've the .1, .2 through the .50....anyone advise?

Andy- I've used everything from CC filters, rubylith, contrast filters, colored cellophane, etc. in Dianas/Holgas/box cameras, etc.

Nice! You happen to know which of the CC yellows is most like a K2? I'm guessing the 0.50

I don't recall which I used. I do remember it was a filter which was damaged, so cutting off a piece wasn't wasting a good filter. Is there a way for you to take a few shots, with each of the filters taped to the front of the camera? That way, you can gauge the results of each.

K2 = Wratten 8
No, you cannot copy the spectral density of the Wratten 8 by using yellow Color Compensating filters.
However, stacking two CC50Y should get you close.
The K2/Wratten 8 contrast filter is a cut-off filter that cuts-off blue and transmits green and red.
The CCY compensating filters are band-pass filters that transmit a band in the yellow region, but still let through some blue.
However the relative sensitivity in that region varies for different films, so that you likely will get similar results.

Thanks AgX! Thankfully the .50 is large enough that I can double it over like you suggest and get close to a K2. Just wanna mess around and have a bunch a these cc filters doing no work...thanks!

All this talk about cutoffs and bandpass… Were you by chance a radio amateur in another life?

Light and radio waves; all part of the electromagnetic spectrum.

How about a piece of Rosco/Lee stage lighting filter gel?
